TESTING-CAP AND CLAMP.

SPECIFICATION forming part of Letters Patent No. 602,281, dated April 1 2, 1898.

I Application filed January 12, 1894- Serial No. 496,624. (No model.)

T0 on whom it may concern.-

Be it known that I, PATRIOKJ. OAHILL, of Utica, in the county of' Oneida and State of New York, have invented certain new-and useful Improvements in Testing-Caps and Clamps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to.

known as soil-pipe, having two branches with three forms of construction of cap and clamp applied. Fig. 2 shows one of the forms of construction of clamp in connection with the cap and packing and end of soil-pipe, the cap end of soil-pipe being shown in section. Fig. 3 shows same parts shown in Fig. 2 from the end of the clamp. Fig. 4 shows a plan view of the clamping device shown in Figs. 2 and 3. Fig. 5 shows a plain edge and partially perspective views of thecap used in connection with the clamp. Fig. 6 shows a plain edge and partially perspective views of the elastic packing ring or gasket used in connection with the device. Fig. 7 shows a modified form of construction of clamp from the side in connection with the cap-packing and section of soil-pipe. Fig.8 shows the same as Fig. '7 on end view of the clamp. Fig. 9 shows aplan view of this clamp. Fig. 10 shows a crosssection thereof on line A B of Fig. 9.

Referring more particularly to the reference-numerals, 1 indicates a section of soilpipe with enlarged ends 2 on its straightaway portion and on each of the branches shown in the usual manner of soil-pipes. For each size of end 2 I provide a testing-cap 3, having a circumferential rabbet 4 for the reception of the packing ring or gasket 5. The top of the cap is provided with an indentation 3 for the reception of the end of the set-screw. The set-screw 6 is provided, as shown in Figs. 2 and 3, in central enlargement of cross-bar '7. On either side of the enlargement are adjustably mounted the hooked arms 8 of a length to extend to and each provided with a pair of hooked fingers 8, adapted to engage under the shoulder 2 of the enlarged end of the pipe. The clamping-arms 8 are secured on the bar 7 by having the same passed through an opening in the head-like end of the arm, which is provided with a set-screw 9 for securing it in adjusted position on the bar. The ends of the bar 7 are provided with a shoulder or stop 7 for preventing the arms from becoming detached from the cross-bar unless the set-screw 9 is let up to a considerable degree, when the arms can be turned over the end on account of the lower side 7 thereof being rounded, as shown. As before stated, the clamp can be adjusted to any desired size 6. When set up, the set-screw 9 causes the arms 8 toproject rigidly from the-cross-bar 7, which is'necessary on account of the shoulder 2 being inclined and tending to throw off the hooks 8. By the provision of two hooks, as 8, a better hold or grip is obtained upon the shoulder of thepipe.

Various sizes of caps 3, each with a gasket 4, are provided for the various sizes to which the clamp may be adjusted.

In the modified form of construction shown in Figs. 7 8, 9, and 10 the main bar 1) instead of being made solid, as in the previously-described construction, is provided with tubular openings to receive the upper horizontal portion a of the hooked arms of this modified form of construction. The hooked arms of this modified form of construction are secured by set-screws e to the main bar b, and the main set-screw 6 is threaded into the middle of the main bar bin the same manner as when a solid bar is used.

What I claim as new, and desire to secure into the middle of the main bar and adapted to by Letters Patent, is press upon the cap, substantially as set forth. 10
